In modalità Mailing List consenti agli utenti di ricevere copie dei propri post

this topic seems related and suggests that users get emails for their own posts:

"Send me an email for every new post" also notifies for self posts

If you enable “Send me an email for every new post” in your account preferences, then you get email for your own posts, which doesn’t make sense IMO. I’m using this setting as a forum moderator to know about everything that’s being posted.
